long distance detection Ultrasonic sensor M18 CM Series

The application of diffuse reflection ultrasonic sensors is very extensive. A single ultrasonic sensor is used as both an emitter and a receiver. When the ultrasonic sensor sends out a beam of ultrasonic waves, it emits the sound waves through the transmitter in the sensor. These sound waves propagate at a certain frequency and wavelength. Once they encounter an obstacle, the sound waves are reflected and returned to the sensor. At this point, the receiver of the sensor receives the reflected sound waves and converts them into electrical signals.
The diffuse reflection sensor measures the time it takes for the sound waves to travel from the emitter to the receiver and calculates the distance between the object and the sensor based on the speed of sound propagation in the air. By using the measured distance, we can determine information such as the position, size, and shape of the object.
